Linnea Privacy bolt installed.

Rather than a standard privacy door lever, you can combine a passage function lever with a privacy bolt above. A privacy bolt is similar to a deadbolt, but it is not keyed and can be unlocked from the outside. This particular model can be unlocked with a coin or slotted screwdriver. Of course it costs a more to use a separate privacy bolt, but if you're after a different look than the standard and are willing to pay a bit more to do it, this is a great option for you. The things you will need to install this particular privacy bolt are:

- 1" Drill Bit
- 5/8" Drill bit
- 1" Sharp Chisel
- A Hammer
- Power Drill

You will also need some alan wrenches, but the proper sizes and mounting screws are provided with the lock.

Measuring the backset for privacy bolt installation

Installing a Linnea privacy bolt is easy to do, but it does have quite a few steps. It's not quite as user friendly as a generic inexpensive lock, but it's not hard. It just takes a bit longer and in the end you'll be grateful you chose this lock and took the time to install it right. The simple square privacy bolt looks clean, modern, and it's fun to have some fancy hardware your guests won't expect. The first thing you need to do to install your linnea privacy bolt is measure and mark where the bore and cross bore need to be. You really can put this anywhere, above or below your doorknob or lever set. I chose to put this one at 4 1/2" CC from the bore hole below. My privacy bolts were ordered with 2 3/8" backset, just like my Emtek Stainless Steel Hermes Levers, so I marked both the bore and cross bore lightly for drilling.

Drilling the cross bore for privacy bolt. Next, drill out your cross bore. I used a wolfcraft drill guide I had kicking around the shop just to help keep the bit nice and straight. It helps, but you don't have to use one. You'll just want to be really careful you keep the drill bit straight. The depth just needs to be enough to fit the latch in the hole completely recessed. The diameter is a standard 1" crossbore used for doorknobs and deadbolts. I used a 1" paddle bit and it handled the job with ease. Take it easy as you drill. Most doors these days have a hardwood edge with composite core. Once you hit that composite, the drill will eat through it much faster. If you're not careful you might have some issues.
Drilling 5/8 bore hole for linnea privacy bolt Once you have drilled the cross bore you can drill the main bore hole for the thumbturn to pass through the throwbolt latch. This hole can be 3/8" - 5/8" in diameter. I used 5/8" just so I had a little more room to play with. I wouldn't go larger than that or it will be difficult to attach the decorative rosettes. The instructions from Linnea actually tell you to bore it at 2 1/8" - do not do this! If you do, you wont be able to install this lock. Their instructions need to be fixed.
Door prepped with bore and cross bore. This is what your door should look like up until this point with a 1" cross bore and 5/8" bore hole. Now we'll move on to prepping for the throwbolt latch.
Mark faceplate area to be removed with chisel Next insert the throwbolt latch into place, center it nicely and mark the door where it need to be chiseled.
chisel out faceplate area Then chisel out the area about 1/8" or a tad bit more so that the latch will fit nice and flush with the door edge.
Install the privacy bolt latch. This is what your throwbolt should look like installed. The latch has a solid mounting plate that is covered with a thinner faceplate in the finish of your choosing. If the thinner faceplate gets tweaked a little as you tighten the mounting screws, you can fold a piece of paper and place it over the faceplate and lightly tap it with your hammer to get it recessed in the mortised area. The paper will protect the metal surface from getting damaged.
Inside of thumbturn The decorative faceplates have a mounting disc that sit behind them. The next step is to mount these plates. To do so you need to also insert the throwbolt spindle and knobs to make sure they spin freely and activate the throwbolt. Once you have verified that they work, attach the disc. You'll notice in the picture that the three holes are in a triangular pattern. You'll want to alternate one mounting plate from the other. So in this picture the single hole is above where the latch passes through, in the next picture the two holes are above the latch passing through. If you don't do this your mounting screws will hit each other, and if they are randomly places, you may hit the throwbolt latch and the mounting screw will not recess completely.
Outside of thumbturn Outside mounting plate. Same as above but as mentioned, opposite triangular pattern for the mounting screws.
Installing decorative rosettes Next attach the decorative rosettes using the allen wrench provided. Make sure the rosette stays parallel to the edge of the door as you tighten.
Install thrumbturn and tighten Then inser the thumbturn and spindle and tighten with the larger allen wrench provided. You'll want to position the outside half of the spindle according to how you want the lock to work. For example, I set this one so that when the door is unlocked, the line on the exterior is vertical, horizontal when locked. You can do whatever you want.
Mark jamb strikeplate for mortising Next mark the location on the jamb where the strike needs to be so you can chisel out the material so it sits flush. To make sure this is in the right place, you can mark the end of the throwbolt with a marker or pencil, then shut the door and turn the latch as if you were locking the door. This should make a mark on the jamb so you can be sure to position the strike in the exact place it needs to be. Then center the strike opening on that mark and trace it with a pen or pencil. Don't make a crooked line like I did or you'll have to clean it off later.
Chisel out faceplate Chisel out the area for the strike about 1/8" deep.
Drill out throwbolt area Now drill out the center area where the actual bolt will recess into the jamb upon locking. I used a 1/2" drill bit and drilled two holes one on top of the other, then cleaned it up with a chisel. Then mount your strike plate and you are done.


You're Finished. Now sit back and enjoy the modern style of your new lock, or if you haven't ordered any yet, check out all of our privacy bolts.
